Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed May ll, 1907. Serial No. 373,084.

To all 'whom it may concern:

Be it known that I, ADA O. MARTIN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Ohurns, of which the following is a specication.

This invention relates to a churn of that type provided with an oscillating barrel adapted to be actuated by a walking beam iiexibly connected with the ends of the barrel. The invention has for one of its objects to improve and simplify the construction and operation of devices of this character so as to be comparatively easy and nexpensive to manufacture, extremely easy to agitate, and conveniently emptied or filled.

A further object of the invention is to provide a rocking frame on which the handle or walking beam is pivoted so that the barrel will have a compound or double movement, due to the oscillation of the frame and of the walking beam.

Another object of the invention is to provide iiexible and elastic connections between the ends of the barrel and walking beam so as to rend'er the barrel extremely free and sensitive in its movements.

With these objects in view and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate one of the embodiments of the invention, Figure l is a side elevation of the churn. Fig. 2 is an end View thereof. Fig. 3 is a View of the cover of the barrel detached.

Similar reference characters are employed to designate corresponding parts throughout the several views.

Referring to the drawing, l designates the uprights of the frame which are provided with rockers 2 and are connected adjacent their top and bottom ends by cross members 3 and 4, thus constituting an ocillating frame.

' Hingedly mounted at 5 on the top cross piece 4 is an 5 as a center and also a rocking movement about the rockers 2.

The barrel 8 is provided with an opening l0 in one head which is normally closed by a disk-shaped cover ll snugly fitting the opening, which cover has a diametrical recess l2 curved outwardly at its ends and adapted to receive bail-shaped locking members 13 hingedly connected at their ends to the head of the barrel, as indicated at 14. On the head is secured, by a bolt l5, an S-shaped clamping member 16 that engages over the members 13, as clearly shown in Fig. 2. In the top side of the barrel is a Vent opening normally closed by a stopper I7, and in the bottom is a drain opening closed by a screw cap or the like 18. At the end of the barrel opposite from that having the opening I0 and on the bottom side thereof is a ring 19 adapted to be engaged by a hook 20 on the bottom cross piece 3, when it is desired to throw the barrel into the proper position for filling or emptying the same.

In practice, the barrel is moved to the dotted line position in Fig. l and secured by the hook 20. The cream to be churned is then placed into the barrel and the cover Il fitted in the opening l0. The members I3 are next swung inwardly to engage in the recess l2 and the clamping strip I6 turned across the member lf3, thereby firmly clamping the cover in place. After detaching the hook 20 from the ring, the churn can beoperated by oscillating the lever 6 and simultaneously imparting a back and forth horizontal movement thereto to oscillate the entire structure on-the rockers 2. By this combined movement, the barrel will be agitated in a simple and thorough manner so that the churning will be quickly effected. After the churning is completed, the buttermilk is first drawn off by removing the cap 18 and then the barrel is moved to the dotted line position and fastened by the hook 20 to permit the cover to be removed and the butter taken out of the barrel.

A churn of the character referred to is comparatively simple and inexpensive to construct and can be made of any size suitable for toys or for domestic use. j

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the. method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with 'the apparatus which I now consider to be the best embodiment thereof, I desire to have it understood that the apparatus shown is merely illustrative and that such changes may be made when desired7 as are within the scope of the claims. u

Having thus described the invention, what I claim is:d

l. In a churn, the combination of a rocking frame, a walking beam mounted on the frame, and a barrel fiexibly suspended on the walking beam.

2. In a churn, the combination of an oscillating' frame, a walking beam mounted thereon, a barrel for containing the cream to be churned, and elastic members flexibly connecting the barrel with the Walking beam.

3. In a churn, the combination of a frame, rockers secured to the frame, a lever fulcrumed on the frame, a

barrel coniaining the Cream to be clinrned, and springs for connecting the ends of the barrel with the lever.

4. In a churn, the combination of a rectangular' vertically disposed frame, rockers on the beam thereof, a lever 5 on the top of the frame, a barrel disposed between the i springs connecting` the Walking beam with the barrel, and l lever, helical extension springs connecting the ends of means for fastening one end of the barrel to the frame to hold the former in n tilted position.

In testimony whereof, I :linx my signature in presence ol two witnesses.

ADA O. MARTIN. the barrel with the lever, and nieans for holding the barrel in tilted position.

5. In n churn. the combination of a frame, a walking l0 beam thereon, :L barrel disposed below the walking' benin,
